ICE-CUTTING MACHINE."

Specification of Letters Patent. Patented A 11, 1916 Application filedMarch 20, 1914. Serial No. 826,091.

To allwhom it may concern:

Be it known that I, JOHN HANSEN, a citizen of the United States,residing at Strong, in thecounty of Chase and-State of Kansas, haveinvented new and useful Improvements in Ice-Cutting Machines, of whichthe following is a specification.

The invention relates to ice cutting machines, and has for its primaryobject to provide a machine of this type wherein the cutting and markingsaws are mounted on swinging frames, one being carried by the other andboth of which are independently and simultaneously adjustable to permitthe varying in thedepth of cutting action thereof in the ice as theoccasion may-require.

Another object of the invention is the provision of an ice cuttingmachine wherein a guide is arranged thereon to engage in the kerf formedby the marking saw so that the machine will be guided in a straight pathand the ice .blocks will be cut with uni formity.

1 A further object of the invention is the provision of a machine ofthis character wherein the supporting sleigh can be readily and easilyturned through the medium of a supplemental runner disposed at rightangles to the sleigh runners and carried at one end of the supportingsleigh.

A still further object of the invention is the provision of a machine ofthis character wherein the heavier side of the same is arranged at aremotepoint from the line of cut in the ice during the working of themachine, thereby avoiding the possibility of the breaking of the icewhilethe machine is traveling thereover.

A still further object of the invention is the provision of a machine ofthis character which is simple in construction, thoroughly reliable andefficient in operation, and ineX- pensive in manufacture.

With these and other objects in view, the invention consists in theconstructiom combination and arrangement of parts as will be hereinafterfully described, illustrated in the accompanying drawing, and pointedout in the claimhereunto appended.

In the drawings :-Figure 1 is'a side elevation of a machine constructedin accordance with the invention. Fig. 2 is a vertical longitudinalsectional view thereof. Fig. 3 is a top .planview. Fig. 4 is anendelevation. Fig.5 is a similar view looking toward the opposite end ofthemachine. Fig. 6is a vertical transverse-sectional view.

Similar reference characters indicate corresponding parts throughout theseveral views in the-drawings.

Referring to the drawings by numerals, the machine comprisesa mainframexforming a sleigh including spaced parallel side runners lO andfront and rear cross sills or beams ll and 12 respectively, the edgesofthe runners 10 contacting-with the ice being 1 provided withsteel-shoes'13 as usual for the easy guiding of thejsleigh over the iceas usual. Swingingly, connected in the main frame is a forwardlyextending swinging frameincluding spaced parallel intermediate andouterlongitudinal beams l land 15 to which are connected front and rear crossbars or beams 16, the-outer beams -15 at their.

rear ends being formed with pintle eyes 17 through which is passed apivot shaft18, the same being journaled in the runners 10 for pivotallyconnecting the said swinging frame tothe main frame.

Mounted; at the forward ends of the runners 10 ofthe main framearevertical up toothed segment 26 to which is pivotally releasing device 29of any desirable form, and thispawl or d0g'28'is adapted to engagethe-toothed segment 26'for locking the lever- 27 in adjusted position.Also loosely connected with thevthrow'leve'r 27 is a shift rod 30,thesame being adjust-ably connected to the crank arm 23 so that on movingthe lever 27 the shaft 21 willbe rocked for the raising f or lowering ofthe swinging frame on the main frame for a purpose presently described.

Mounted in bearings 31 secured to the swinging frame near the forwardend thereof is a shaft 32 which has fixed to one end an ice cutting saw33 of the circular type, the same being disposed slightly beyond oneside of the main frame and is adapted to cut the ice over which themachine travels when being moved forwardly or backwardly thereon.

Supported in the swinging frame is a rearwardly extending swinging frameor hanger 34 which has its limbs connected to a pair of the longitudinalbeams of the said swinging frame by means of pivots 35, and carried nearthe free end of this frame or hanger 34 are bearings 36 in which isjournaled a stud shaft 37 carrying an ice marking saw 38 of the circulartype, the latter being designed to form a kerf in the ice during thecutting action of the saw 33, the said marking kerf being spaced adistance from I the line of cut of the saw 33 and extends paralleltherewith and in which is adapted to be engaged a guide device presentlydescribed.

Fixed to and rising from the swinging frame are uprights 39 formed withbearings 40 in which is journaled a rocking shaft 41 formed with crankarms 42' and 43 respec tively, to one of which is loosely connected alink 44, the same being loosely connected to the free end of the hanger34, while the arm 44 has loosely connected thereto a shift rod 45, thesame being loosely connected to a throw lever 46 pivoted at 47 to avertically disposed toothed segment 48 fixed to the main frame near therear end thereof. The throw lever 46 carries a locking pin 49 engageablewith the toothed segment 48 for locking the said lever 46 in adjustedposi-' tion, the pin 49 being connected to hand releasing device 50whereby the lever 46 can be unlocked for the moving thereof to shift theshaft 41 for the raising and lowering of the hanger 34 whereby themarking saw 38 will cut a deep or shallow kerf in the ice during theworking of the machine.

It will be noted that the swinging frame pivoted to the main frame 10and the frame or hanger 34 pivoted to the said swinging frame can beindependently raised or lowered, yet on the. raising of the swingingframe pivoted to the main frame the said frame or hanger 34 will beraised therewith as will be apparent, thus the said swinging frames canbe simultaneously adjusted, that is, by the raising and lowering of theframe pivoted to the main frame.

Mounted upon the swinging frame connected to the main frame at itspivoted end is a driving motor 51 to the driving shaft 52 of which isfixed a belt pulley 53 over which is trained a belt 54, the same beingalso trained over a pulley 55 fixed to the shaft same being also trainedover a pulley 58 fixed to the shaft 37, it being seen that on theworking of the motor 51 motion will be imparted to the shafts 32 and 37for the simultaneous rotation of the same to operate the saws carriedthereby. It will be noted that on the raising or lowering of either ofthe swinging frames the belts 54 and 57 will not be disturbed by eithertightening or slackening thereof on the pulleys over which the same aretrained.

Mounted at the rear end of the main frame at right angles to the runners10 thereof is a supplemental runner 59 which is pivotally supported uponthe rocking levers 60 pivoted at 61 to the said main frame, one of thelevers terminating in a handle 62 whereby the supplementalrunner 59 canbe moved for the raising and lowering thereof. This supplemental runner59 when lowered permits the turning of the supporting sleigh in an easyand convenient manner.

Carried on one of the runners 10 is a guide device comprising a rod 63journaled in bearings 64 fixed to the said runner, the rod 63 beingformed with arms 65 which are positioned near the front and rear ends ofthe main frame and carry stationary rudders or guide plates 66 which areadapted to engage in the kerf cut by the saw 38 when the machine hasbeen shifted from the line of out executed by the saw 33 so as to guidethe machine in a straight course to effect the cutting of the ice inblocks of uniform size. It will be apparent that the marking device canbe raised for disengaging the kerf formed by the saw 38 or to bring itout of Contact with the ice when it is desired to transport the machinefrom one point to another. The machine can be driven from the motro 51in any desirable manner if found desirable.

From the foregoing it is thought that the construction and manner ofoperation of the device will be clearly understood, and therefore a moreextended explanation has been omitted.

What is claimed is In a device of the class described, in combination, arectangular frame, runners secured to said frame, a rod extendingtransversely of said frame toward one end, a longitudinal frametrunnioned upon said transverse rod whereby to swing thereupon, a shaftmounted upon said swinging frame at its end opposite to said rod, an icecutter mounted upon said shaft, bearings secured upon the outer face ofsaid first named frame, a rod journaled in said bearings, U- shapedmembers formed integrally at the opposite end of said rod, 2. rightangular offset formed upon said U-shaped members, said swinging frame,and means on said 10 guide bars carried by said offset in perpenswingingframe for rotating said ice cutter.
